Bending an Object into a Sphere
Another approach:


Just to tidy up, select all edges, CtrlE > Edge Data > 'Clear Sharp'
Assign a Subdivision Surface modifier with the 'Simple' option (1 or 2 levels)
Assign a Cast modifier, 'Sphere' option, Factor: 1




You can apply the modifiers to bake them into the mesh, if/when you need to, (in order, top to bottom)..

You can assign an 'Edge Split' modifier above the others, if you need to split out the surface tiles,
and apply it followed by  P > separate by Loose Parts if you need the tiles to be separate objects
